We consider a two-sector two-periods overlapping generations model with inelastic labor, consumption in both periods of life and homothetic CES preferences. Assuming gross substitutability and a capital intensive consumption good, we prove that when dynamic efficiency holds, local indeterminacy...

We study optimal government spending in a business cycle model with frictional unemployment. The Ramsey optimal policy is contrasted with a reference policy which would be first best in a frictionless economy. Results are: the Ramsey policy i) implies a higher steady state ratio of government...

We study the consequences of non-neutrality of government debt for macroeconomic stabilization policy in an environment where prices are sticky. Assuming transaction services of government bonds, Ricardian equivalence fails because public debt has a negative impact on its marginal rate of return...
